NU313 is a cylindrical roller bearing, 65 mm bore × 140 mm OD × 33 mm wide (2.5591 × 5.5118 × 1.2992 in).
The NU313 is a single row cylindrical roller bearing with dimensions of 65mm bore diameter, 140mm outside diameter, and 33mm width. This bearing design features high radial load capacity and allows for axial displacement of the shaft relative to the housing, making it suitable for applications where thermal expansion must be accommodated.
